Exchangeable item

An exchangeable item is a category of item which serves no in-game purpose aside from being able to be traded for another item or some sort of service. Though several key items fall under this category (such as Generation I and Pokémon FireRed and LeafGreen's Bike Voucher), their exchange is often important to the story of the games, so they are not included here. These items are often also valuable items.

Due to a mistake in the Nintendo Power Pokémon Diamond and Pearl guide, there was a rumor that the Shoal Salt functions like the Leftovers. However, multiple tests in-game have shown that the Shoal Salt does nothing; it is in fact the Shell Bell that functions similarly to Leftovers, itself created in Generation III from four Shoal Salts and four Shoal Shells.

In Pokémon X and Y, the Heart Scale was incorrectly sorted in the Bag as an evolutionary stone when the bag is sorted by type, instead of as an exchangeable item.
